rules

Hi!
I try to learn how to create rules in postgres, but something goes wrong,
cause nothing happens (or eventually some errors).
I have two tables
create table one (
    one_id     int4 primary key not null default nextval('schem_seq'),
    one_name text,
    one_lock text
);

create table many (
    many_id            int4 primary key not null default
                nextval('schem_seq'),
    many_onef        int4 not null, //this is foreign key equal
to one_id from one table
    many_name        text,
    many_lock        text
    );

I try to create two rules
-first one on update one_id in one table
CREATE RULE rupd_one AS ON UPDATE TO one
    DO UPDATE many
        SET many_onef = new.one_id
        WHERE many_onef = current.one_id;

-second one on delete record from one table
CREATE RULE rdel_one AS ON DELETE TO one
    DO DELETE FROM many
        WHERE many_onef = old.one_id;

In short these two seem don't work. I'm not sure of either syntax or some
other errors - psql at first rule don't report any errors, just output
UPDATE 0
and second one usually something like this:
PQexec() -- Request was sent to backend, but backend closed the channel
before responding.
        This probably means the backend terminated abnormally before or
while processing the request.
    Thanks for any response
